- Description: The aim of the study was to carry out an assessment of the recruiting and selection processes at KSD Local Municipality in the Eastern Cape Province. The study, also aimed to give recommendations on how organisations can improve their human resource recruitment and selection processes in order to employ and retain quality or highly talented and committed employees, and to offer good service delivery to the people. The recruitment and selection practices at KSD Local Municipality seem to be degenerating. Lack of transparent procedures in the hiring of workers can result in the municipality experiencing a decline in performance and an increase in service delivery protests. Cases of nepotism and corruption in the hiring process has negatively affected the operations of the municipality The study used the quantitative research methods for data collection and analysis. Thus, the questionnaire was used to collect data and the probability sampling method was used to get the respondents. The stratified sampling method was employed in selecting respondents. This study concluded that the hiring procedures at KSD Local Municipality were not good. Good hiring processes improve employee engagement, retain quality workers, reduce employee turnover and service delivery protests, and save time and money. Poor recruitment and selection procedures increase employee turnover, lower employee morale and level of performance, reduce employee confidence in the management and may result in extra costs being incurred. Recommendations have been prepared on how organisations can employ good recruitment and selection practices that promote the employment and retention of quality employees. The municipality should design and implement good and up-to date hiring procedures which are devoid of corruption and nepotism.

- Description: Poverty and limited livelihood options remains a huge challenge in Africa, particularly in Zimbabwe. The study investigated the effectiveness of the Harmonized Social Cash Transfer programme in improving household economy and strengthening livelihood options in Zimbabwe with a particular focus on Mangwe District. In order to come up with a comprehensive investigation, the researcher grounded the study in sustainable livelihood approach and the capabaility approach. Due to persistent poverty and people adopting precarious coping strategies in Zimbawe, the government and NGOs collectively came up with a comprehensive cash based poverty alleviation strategy to alleviate poverty and build on peoples livelihood options which is the cash transfer programme. The study utilized a qualitative methodology, based on its ability to provide a contextualized description of people’s perspectives, feelings and opinions in terms of how a programme affected them. The evaluation sought to find out whether the cash transfer programme achieved its objective of strengthening household economy. The study established that the Harmonized Social Cash Transfer programme made some positive inroad towards strengthening household economy, however, lack of stakeholders coordination, collapsed economy, pollitically motivated moves from the ruling party caused the programme to fail. As such, the poor Mangwe people are still continuing engaging in precarious coping strategies, such as, selling assets, eating less than one meal per day and venturing into prostitution. The study therefore, calls for the government to review the household size vs cash scale and regularly review the amount of money received to be in line with current prices of commodities

- Description: This study is premised on explaining perceptions of Nkcunkcuzo and Tholenicommunity members towards factors influencing muthi killings in Butterworth, Eastern Cape (E.C.). The villagers of the two selected areas have recently experienced number of incidents. It is against this background that this study sought to establish the explanations by soliciting direct experiences of community members on incidences of muthi killings.A plethora of research projects have been previously conducted to understand this phenomenon with the Criminal Justice System (CJS) having its own perspective regarding the muthi killings. However, the researcher deemed it imperative to have explanations of community members’ perceptions of the related factors thereof. The objectives that guided this study mainly included: (1) to establish the explanations of Tholeni and Nkcunkcuzo community members on the factors that influence muthi murders, (2) to determine why people in Tholeni and Nkcunkcuzo commit muthi murders and (3) to illustrate the medus operandi of muthi murderers in Tholeni and Nkcunkcuzo. The qualitative research methodology was employed in the study. Purposive sampling was used in the selection of selected participants and respondents of this study and data was collected through self-administered questionnaires and conducted interviews by the researcher. This study established that it is rich people and politicians who are most probably reasons for incidents of muthi murders in Etholeni and in Nkcunkcuzo. Business people want to accumulate their wealth and get rich using muthi. The belief behind this is that when muthi is mixed with human body parts it is bound to be strong eventually attracting more people (customers) to the businesses owned by these people. Ultimately this leads to profit accumulation. On the other hand, the involvement of politicians in the incidents of muthi killings is mainly associated with maintaining political power by remaining as centres of preference to the community members. The participants have echoed the same sentiments on the factors that influence muthi murders in Tholeni and Nkcunkcuzo villages, Butterworth in the Eastern Cape. vi Finally, this study recommended as follows: The Etholeni and Nkcunkcuzo community leaders must work hand in hand with the government to establish centres where children, older persons and people with disabilities, particularly those who are without people to protect them, can be institutionalised in order to guarantee their safety; The chiefs of Tholeni and Nkcunkcuzomust collaborate with the social service professionals in order to address the issues of mistrust among community members through community development programs; The community policing forums of Tholeni and Nkcunkcuzo must be capacitated and their knowledge strengthened by the criminal justice agencies on muthi murders to avoid confusion about muthi murders with other different types of murders; The government of South Africa must formulate an elementary social curriculum on muthi killings in order to educate the villagers on the muthi killings from a criminal justice point of view; The legislative framework must be reviewed in order to impose harsher sentences to the muthi murderers and the accomplices thereof; There must be social welfare organizations in Tholeni and Nkcunkcuzo villages in order to take care of those children that have lost their care-givers due to muthi killings; The traditional leaders of Tholeni and Nkcunkcuzo must formulate a charter for community norms and standards to circumvent the use and selling of drugs in the concerned communities/villages. More research projects must be funded in order to get a full understanding of the causes of muthi killings and to provide a word of scientific reason to the criminal justice system, particularly as it relates to muthi killings in South Africa.

- Description: This study sought to investigate social factors contributing to intimate partner violence in Tentergate village. Intimate partner violence or intimate personal violence, a matter once considered private, has gained increased attention as a public health crisis. In their efforts to better understand and prevent this behavior, social science researchers have discovered the link between gender inequality, early exposure to violence, spousal abuse and family conflicts. This paper uses social feminist, social learning and family violence theory to explain intimate partner violence. Participants‘ perceptions were assessed through systematic analysis. Quantitative and qualitative analysis was done on data obtained from interviews conducted on 30 women informants. The study revealed that there are several social factors contributing to intimate partner violence. In the final analysis, it argues that effective treatment and prevention should include both criminal justice and public health strategies.

- Description: The study was looking at the Free Basic Water policy (FBWP) in the Eastern Cape which was introduced in July 2001 in South Africa. FBWP was introduced to all provinces, however people living in rural areas, poor areas and villages are still suffering from lack of clean and safe drinking water. People lack adequate supplies of water and this creates conditions under which the diseases thrive. The researcher used mixed research methodology which comprises of qualitative (interview) and quantitative (questionnaire) approaches. The reason for the use of mixed methodology was to get adequate information both from the municipality (the provider of water) and the residents (the receivers of the services provided by the municipality) in order to assess how the unreliable water provision affect residents and the challenges being faced by the municipality in providing water. The findings of the study are that both people under Golf course and Bhofolo have little knowledge about FBW and most of the residents are unable to pay their water bills. Residents in the two research areas suffer from medical problems due to unreliable water provision. The study is therefore, of view that South Africa needs to prioritise improvement of access to water in rural areas, poor areas and villages. There is a need to educate people about FBW and on how to save water.

- Description: Since the Department of Correctional Services has been transformed into an institution of rehabilitation and skills development, there is a need for a sound classification system whereby offenders are classified according to their potential for treatment and training programmes that match their risk/needs. The study was conducted in Middledrift Correctional Centre in the Eastern Cape with the aim of examining the effectiveness of correctionally based vocational training programmes towards reducing recidivism. Research towards correctional programmes was necessitated by the extant of recidivism in South Africa. The question is where does the problem lie because offenders are provided with rehabilitation programmes to make them law abiding citizens and reintegrate well into the community up on release but, in many cases it does not become possible as many ex-offenders return to custody either for new offence or parole violation. The study used qualitative design in data collection and in explaining the results. A sample of sixteen recidivists and five correctional officials formed participants for the study selecting using purposive sampling procedures. Involvement in vocational programmes was used as a criteria for selectiong of correctional officials as participants. In-depth interviews were conducted with eight recidivists and all five correctional officials and a focus group interview was held with the other eight set of recidivists. The study examined the impact of vocational programmes on recidivism followed by the factors that hinder effective offender rehabilitation and factors that influence recidivism up on release. The findings of this study were analysed using thematic analysis with the assistance of a voice recorder as a back up for collected data. Findings revealed that a small number of recidivists attend vocational training programmes and these programmes vi (vocational) are short in the centre together with programme facilitators at the time of reporting. Offenders stated that the available vocational programmes are of no interest to them. Participantas stated that vocational training does assist in desisting criminal activities up on release as it provide skills and opportunities for employment to curb unemployment as indicated as a major factor influencing recidivism. Findings also revealed that periodic re-assesment is not adequately conducted and classification for vocational training is not likely to be sufficiently done according to offender risk/needs. The study recommends that, a large number of offenders be provided with vocational training programmes and that offender classification incorporate the principles of RNR model

The study adopted a qualitative method. The data was collected through semi-structured one-to one interviews from 16 participants using systematic random sampling. The findings revealed that GBV is prevalent in Duncan Village. Most of the women residing in Duncan Village are dependent on child support grant and raise their children alone without the support of their biological fathers. The study further revealed that GBV against women often happens during day time and the victims are either married or single women. One of the contributing factors of GBV is unemployment. Therefore, this study recommends that awareness of GBV should be made continuously in communities by the government and stakeholders. In addition, the Commission for Gender Equality and NGOs that deal with GBV should be visible in all wards so that their services are known and utilised. The Department of Women Affairs should be the main driver in ensuring that women from previously disadvantaged communities are economically empowered, for example, by initiating income generating projects. However, they too should first be capacitated on business and financial management skills.

- Description: The emergence of urban social movements in the Zimbabwean context is mainly attributed to the political economic crisis, which resulted in the decline of municipal services and other socioeconomic rights central to the ordinary people. In the rural areas many scholars have alluded to the failure of the state to institute a radical transformation of the rural areas as the reason for the emergence of land movement and the subsequent land revolutions that followed in the early 2000s. Within this context, this study sought to investigate the social and structural basis for the emergence of social movements in Zimbabwe. The argument of this study hinges on the central premise of the political opportunity structure approach, which states that the emergence and success of social movements depends on certain political opportunities within the political environment. Building upon the guidance of the qualitative paradigm, whose method of investigation includes in-depth interviews and focus group discussions, the findings illustrate that the emergence of rural social movements in Zimbabwe was mainly to address the land question; such initiatives were to be done through fighting imperialism that hinges upon neo-liberal policies. In addition, one of the objectives for the emergence of rural social movements was to complete the objective of the liberation war, which was to give back the land to the indigenous black people. The tactics of the rural social movement included engaging the state and confronting it in other instances. Further, illegal land occupations were also one of the tactics of this movement. Ideologically, the movement used a Pan-African ideology to confront neo-colonization. On the other hand, the findings of the study illustrate that the emergence of urban social movements was mainly to provide a platform for the marginalized people to voice their discontent of the decline of service delivery in the urban context. Since most of these aspects were linked to the broader economic crisis facing the country, urban social movements also intended to initiate a political transition. The tactics of urban social movements included disruption, the establishment of networks with other social movements and the use of media, while constructing their ideology within the human rights framewo

- Description: This study analyzed the effects that spatial arrangement of petroleum products retail outlets and the supply chain management techniques employed for products distribution (for both intra city and intercity shipments) have on the retailing dynamism of petroleum products within built environment and peripherals of Ibadan metropolis over the years. Specifically, the study investigated the differentials in the spatial configurations of petroleum products retail outlets between the core and periurban zones of the metropolis. An attempt was made to determine the explanatory variables that influence the spatial distributional decisions of petroleum products retail outlets in the metropolis. The study equally examined how the supply chain management (SCM) techniques by the different categories of the retail outlet owners influence the efficient and cost effective distribution of petroleum products. Lastly an attempt was made to analyze the relationship between the socio-economic attributes of the haulers and the achievement of compliance to the HSE stipulations guiding the conveyance of petroleum products. The theoretical underpinnings for the research were a derivative of the amalgamation of normative and psychological theories from geography, psychology, SCM and retailing science. Specifically, Expectation Disconfirmation Theory (EDT), Distributive Justice, Central Place Theory (CPT) Theories of Urban Impact (TUI) and Theory of Constraint (ToC) were the theories utilized in the study. For the achievement of the first objective which was to investigate the possible differential in the compliance rate between spatial pattern of fuel retail outlets in the core and peripheral zones of Ibadan metropolis, the first hypothesis of the study (which examined if there was no significant difference in the rate of compliance to the planning authority stipulations guiding the location pattern of petroleum product retail outlets between those located in the built up and xxiv peripheral zones of the city), was tested through the use of buffering and proximity analyses in the ArcMap environment of ArcGIS 10.1, while inferential statistical tool of an independent-samples t-test was conducted to compare the rate of compliance to the stipulations guiding the locations of these outlets in both the core and the peripheral zones. The result from the GIS analysis indicated that 33 (15.56%) out of the 220 outlets in the core zone of the metropolis complied with the planning stipulations guiding the location of fuel retail outlets. For the peripheral zone, out of the 220 fuel retail outlets 24 (10.90%) complied with the stipulations. The result from the t- test which was employed to test the hypothesis indicated that no significant difference existed in the rate of compliance t (263) =-2.66, p = 0.08 between fuel retail outlets in the core zone (M=3.9, SD=1.4) and peripheral zone (M=4.5, SD=1.79). The alternate hypothesis which stated that ―no significant difference existed in the compliance rate between fuel retail outlets located in the two zones‖ is accepted. For the achievement of the second objective of the study which was to analyze the factors which determine the location of fuel retail outlets both in the core and peripheral zones of Ibadan metropolis. All the managers/owners of the 432 fuel retail outlets in the metropolis were sampled out of which 256 questionnaires were retrieved for the purpose of this analysis. The breakdown of the socio-economic characteristics of the sampled respondents showed that the gender distribution showed that 194 (75.78%) of the respondents were males, while 64 (24.22 %) were females. The average age of the sampled population was 33.70 years. The mixed method was employed for the achievement of the second objective of this study. Logistic Regression Model (LRM) was employed to test the hypothesis and the result revealed that the inclusion of the independent variables in the model increased the overall level of it accuracy. The overall significance revealed that the Model Chi- xxv Square, derived from the likelihood fitted is also accurate (X2 = 43.47, df=5, p>.05). The model chi-square value of 43.47 (approximately 44% ) was significant. Thus, the indication is that the model has a good fit in predicting the possibility of a fuel retail outlet being located in the core or peripheral zone of the metropolis as determined by the explanatory variables (the independent variables accounted for about 44% of possible factors which determined whether a fuel retail outlets is located either within the core or peripheral zones of the metropolis. The remaining 56% are factors not considered in the study). The result gotten from the in depth interview sessions corroborated the findings from the tested hypothesis. The third objective was to examine the effects which the supply chain technique employed (either vertically integrated model or third-party arrangement) has on the achievement of efficient and effective distribution of the products. In order to achieve this objective, all the 389 registered members of Petroleum Tanker Drivers (PTD) association who are members of the PTD in the metropolis were sampled, 265 (around 70%) of the distributed questionnaires were retrieved and used for the analysis. In depth interview sessions were also conducted with three different managers of the three major conglomerates in the downstream sector of the Nigerian petroleum sector. The result of one-way between subjects (ANOVA) which was conducted to compare differences in the management and performances of haulage services outsourced to the 3PLS and those run under VIM showed that there was a significant effect of ownership type on management performance (F (2,262) = 60.26, p<.05). The null hypothesis was therefore rejected while the alternate hypothesis was accepted. The findings from the interview sessions posted similar results. The fourth and final objective was to analyze the effect that the socio-economic attributes of the participants (haulers and managers of retail outlets) involved in the distribution of xxvi petroleum products has on the safe, efficient and cost-effective distribution of product and this was done through the use of descriptive statistics, inferential statistics and incisive analysis of the interview sessions. A total number of 265 (70%) out of the 389 registered members of Petroleum Tanker Driver Association (PTDA) participated in the study. Multiple regression analysis (MRA) was used to test this hypothesis. The result from the statistical analysis show that the use of stimulant, work condition, marital status and educational attainment/literacy level have joint influence on compliance (R2 = 0.31, F (4,260) = 29.72, p<.05). On the basis of the foregoing, the hypothesis is thus accepted. The result from the interview sessions confirmed the existence of strong relationship between the explanatory variables and the hypothetical dependant variable. The study recommended a review of the planning processes guiding the establishment of fuel retail outlets. The study also advocated that retailers should endeavour to have stronger control over the supply chain of their products this could done by investing more in VIM rather than outsourcing such functions to 3PLs. This will help in better business performances. Government agencies in charge of monitoring drug abuse among haulers are advised to be more proactive by the duo of prevention and punishment strategies. This should include advocacy campaign against drug abuse. Different ranges of punishments should also be meted out for individual haulers found culpable.

- Description: This study analyzed the effects that spatial arrangement of petroleum products retail outlets and the supply chain management techniques employed for products distribution (for both intra city and intercity shipments) have on the retailing dynamism of petroleum products within built environment and peripherals of Ibadan metropolis over the years. Specifically, the study investigated the differentials in the spatial configurations of petroleum products retail outlets between the core and periurban zones of the metropolis.

- Description: Cases recorded with high blood pressure are a major concern in both public and private hospitals. Adequate provision of health information of patients relating to high blood pressure in Eastern Cape Hospitals hinges so much on the outcome of statistical analysis results. The usual statistical methodologies become inadequate in handling statistical analysis of data collected due to incomplete patients’ information stored in the hospital database. From time to time, new methods are developed to address the problem of missing data. High blood pressure is linked to a lot of diseases such hypertension, cardiovascular disease, kidney disease and stroke. In this study, we developed a new method for addressing the problem of missing data in assessing model used for estimating missing values in terms of minimum errors(using RMSE, MAE, and SE) and goodness-of-fits(using 2 R and adjusted 2 R ) of this model and P-value. . The study compared six different methods: Original data (OD), Listwise deletion (LD), Mean imputations (MEI), Mean above (MA), and Mean above below(MAB) and two steps nearest neighbour (2-NN).The comparison was performed using original data set, and missing values at 5%, 10%, 20%, 30% were simulated on Framingham risk scores under MCAR and MAR simulation on BMI values given some assumptions. Five performance indicators were used to describe the model minimum errors and goodness of fit for all the methods. The results showed that the 2-NN is the best replacement method at lower levels (5% and10%) of missing values while MA and MEI performed best at higher levels(15% and 20%) of missing values. All comparison was based on estimates closest to those of the original data where no value was missing. MAR results showed that 2-NN performed better than LD,MA,MAB, and MEI at 5%,10%, and 20% levels of missing data in terms of absolute difference in p-value to original data.

- Description: The study investigates the Archives and Records Management Programmes (ARMP) in the University of Fort Hare (UFH) and Rhodes University (RU). The task of managing huge quantities of records and archives material is not an easy task when people have to use limited resources. The Research Objectives of the this study was to find out types of records created, received and maintained by university archives and records management programmes at University of Fort Hare and Rhodes University. Establish the available infrastructure for ARMP at the UFH and RU. Find out the legislative and regulatory frameworks that govern the ARMP at the UFH and RU. Identify challenges if there are any facing ARMP at the UFH and Rhodes University. Interviews and questionnaires were two research instruments used in this study to collect data; additional data was collected by reading relevant documents gathered on both institutions and on their website. In this study, the sample was 26 respondents from both universities. The study dealt with administrative staff who deal with records management: Records managers/Officers and Archivists at both institutions. viii Data collected was coded and analysed using Statistical Package for Social Sciences (SPSS) and the findings were presented using pie chart , graphs. The triangulation approaches involves using more than one method to collect data and it is a way of assuring the validity of research with variety of methods to collect data. Findings revealed that respondents were unaware of ARMP in the university. And also some of the findings were the infrastructural needs such as the Lack of records storage, space, Records Preservation facilities (RH, Light), Personnel Training and Development. The challenges facing ARMP in universities includes: a lack of programmes to manage records and archives material, absence of policy that regulates archives and records keeping in the universities understudy, the existing infrastructure at hand cannot meet the requirements for regulatory framework on records and archives management. Based on these challenges mentioned above, the study recommended that both institutions should improve their infrastructure as to be able to preserve the archival material. Training and retraining of staff among others should include use of technology, filing, records creation, maintenance and disposition

- Description: The quality of teacher education seems to have become a crucial point of debate worldwide. However, teaching seems to be one of the careers without a recognised apprenticeship. Therefore, mentoring has been seen as an appropriate way for experienced teachers to guide, assist, coach and motivate teachers in their teaching capacity. Teaching capacity is described as having a broad content which can be related to quality teaching, teacher effectiveness and teacher behaviour in the classroom or in the school. The lens with which the study was viewed was through Lave and Wenger’s (1998) theory, Community of Practice (CoP). Community of Practice is defined as a process of social learning that occurs when people who have a common interest in a subject or area collaborate over an extended period of time, sharing ideas and strategies, determining solutions and building innovations. The study used mixed methods and concurrent triangulation design in sampling 60 participants for quantitative data and 6 participants for qualitative data. The unit of analysis were novice teachers who were randomly and purposively selected. Data gathering methods included questionnaires, classroom observations and document analysis. The focus was on the primary schools, Foundation Phase (FP) novice teachers. The findings revealed utilisation of different mentoring approaches such as one on one; Foundation Phase Team and school- based mentoring. Although the study reveals that the work of the mentor teachers and novice teachers has evolved to include Learning Teams to improve the teaching capacity of teachers; some mentoring approaches were less effective. The study suggests, therefore, that schoolbased and district-based mentoring programmes to be formally organised as part of developing novice teachers’ teaching capacity.

- Description: Geometry prepares learners by equipping them with the knowledge to use higher order thinking skills. The purpose of this research was to assess the difficulties in the teaching and learning of geometry in Grade 9 based on the van Hiele theory in a rural education district in South Africa’s Eastern Cape Province. van Hiele levels complement each other and therefore, geometry educators need to have good pedagogical content knowledge and apply effective teaching and learning strategies to promote geometry learning. The study adopted the pragmatic paradigm and mixed method approach. Convenient sampling based on proximity to the researcher’s workplace was used to select three schools in Komga education circuit for data collection. The educators’ sample consisted of the Grade 9 mathematics educators from each of the three schools making up a total of 3 educators. The learners’ sample consisted of 27 Grade 9 learners,9 from each of the same three schools from where the educators were selected. Quantitative data were collected from educators and learners using different questionnaires. Qualitative data were collected using different in-depth interview schedules for educators and learners. All members of the sample were interviewed. Observations also were carried out in the classroom during teaching and learning of geometry in order to probe the use of strategies by educators. The quantitative data were subjected to descriptive statistical analysis and tabulated. The qualitative data from interviews were thematically analysed and observation data were transcribed, analysed and tabulated. Final conclusions were drawn through triangulating the different data sets. Findings revealed the strengths and weakenesses of the strategies used by educators and the difficulties faced by the learners. Some of the prominent strengths for educators’ strategies were: ability to promote interactive learning and facilitating a conducive environment, enhancement of critical thinking and development of learners’ confidence through participation. Some of the prominent weakenesses of educators’ strategies were:lack of understanding on how to deal with slow learners and inability to change teaching methods to accommodate all learners, thus inhibiting inclusive education.The prominent strenghts for learners were eagerness to participate in all activities and exhibition of confidence in problem solving. The prominent weakenesses of learners were that the respondents struggled with the P a g e | ii geometrical vocabulary and language needed to express their understanding, deficiency in the understanding of geometric concepts and not having the required understanding of the characteristics of triangles. The study recommends that the geometry educators should plan activities for geometry lessons that will encourage the development of geometric vocabulary among their learners. Geometry educators also need to to include questions in their assessments that test conceptual understanding. In-service workshops should be conducted to equip the educators about how to deal with inclusive education.

- Description: This dissertation sought to review literature on the skills underutilisation in the Eastern Cape Department of Education, a case of Head Office –Zone 6-Zwelitsha. The study intended to delve deeper into the depth of this challenge and understand the effects of this misdeed on the policy implementation in the department. This problem was compounded by the lackadaisical approach to the skills development by the department as it seemed to be employing a shotgun approach to the training and education of its labour-force. The consulted literature pointed to the existence and commonness of the skills underutilisation and its occasioning in reduced outputs and low worker-morale in the workplace. This study played a crucial role in terms of its contribution to the body of knowledge, being a reference point not only for the department of education, nonetheless, for other departments and organisations as well. The study could help the department to rectify its weaknesses and deal with their current challenges of personnel underutilisation. Policy makers and consultants could use the results of this study to formulate policies for their institutions. Lastly, students could also benefit from this study by using it as a source of reference. The qualitative method and case study as a research design employed in the study, semi-structured interviews used as a data collection method, snowballing sampling procedure used. The employees of the Department of Education used as the respondents in the study. The empirical findings in the study revealed the multiplicity of challenges associated with misplacement of qualified personnel in the department which entailed, inter alia, poor implementation of policies, programs and projects, low staff morale, poor delivery of services to the departmental clientele.

- Description: This dissertation sought to review literature on the skills underutilisation in the Eastern Cape Department of Education, a case of Head Office –Zone 6-Zwelitsha. The study intended to delve deeper into the depth of this challenge and understand the effects of this misdeed on the policy implementation in the department. This problem was compounded by the lackadaisical approach to the skills development by the department as it seemed to be employing a shotgun approach to the training and education of its labour-force. The consulted literature pointed to the existence and commonness of the skills underutilisation and its occasioning in reduced outputs and low worker-morale in the workplace. This study played a crucial role in terms of its contribution to the body of knowledge, being a reference point not only for the department of education, nonetheless, for other departments and organisations as well. The study could help the department to rectify its weaknesses and deal with their current challenges of personnel underutilisation. Policy makers and consultants could use the results of this study to formulate policies for their institutions. Lastly, students could also benefit from this study by using it as a source of reference. The qualitative method and case study as a research design employed in the study, semi-structured interviews used as a data collection method, snowballing sampling procedure used. The employees of the Department of Education used as the respondents in the study. The empirical findings in the study revealed the multiplicity of challenges associated with misplacement of qualified personnel in the department which entailed, inter alia, poor implementation of policies, programs and projects, low staff morale, poor delivery of services to the departmental clientele.

- Description: In this present study, the phytochemical compounds, antioxidant activities, and cytotoxicity potentials of solvent extracts (polar solvents) of Leonotis leonurus (L. leonurus) and Boophone disitcha (B. disticha) commonly used in the management of Alzheimer’s diseases in Hogsback, in the Eastern Cape, South Africa were investigated. The phytochemical compounds were determined by standard protocols of Folin–Ciocalteu method, aluminium chloride colorimetric method as well as Mayer’s and Wagner’s method. The antioxidant capabilities were assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and nitric oxide radical scavenging assays. The majority of extracts from both plant species exhibited free radical scavenging potential for oxidants they were tested against viz; DPPH, hydrogen peroxide, ABTS and nitric oxide. They further displayed good reducing potential against ferric iron. The results have shown a concentration-dependent dose of inhibition/scavenging activity (in DPPH, hydrogen peroxide, ABTS and nitric oxide assays) and reducing ability (in ferric reducing assay). However, leaf extracts of L. leonurus displayed ineffective scavenging activity against nitric oxide whereas extracts from L. leonurus flower and B. disticha bulb had higher scavenging potential against the production of nitric oxide radical. The GC-MS profiles of the plants extracts revealed the presence of numerous bioactive compounds that are known to possess excellent anti-inflammatory and most importantly antioxidant properties. Another interesting observation of GC-MS analysis data was the presence of compounds reported to inhibit Acetycholinesterase (AChE), which is a key enzyme targeted in the treatment of Alzheimers’ Disease (AD). The cytotoxicy tests for these extracts were carried out in order to assess the potentential detrimental effects on human health using Alamar Blue assay. It was noted that an increase in the extract concentration of both plant species resulted in a noticeable decline in cell population. These extracts were then declared xix to be quite toxic against HeLa (human cervix adenocarcinoma cells) cells as the cell viability in some extracts was quite low. Hence, toxicity testing of the studied plants’ extracts against normal cells is highly imperative in the future study. The results from this present study scientifically validated the use of the studied plants in folkoric medicine for the management of Alzheimer’s diseases.

- Description: Aim: The purpose of the study was to assess the quality of patient care in the Primary Health Care (PHC) facilities of Mnquma Sub-district with the goal of improving or maintaining quality nursing in the area. Methodology: This study followed a quantitative research approach and it is descriptive in nature. The study involved 561 participants, of whom 406 participants were from urban clinics and 155 were from rural facilities, all these participants were attending clinics at Mnquma Sub-district. A structured questionnaire was used for data collection, since the participants were able to read and write in either English and or IsiXhosa. The data was analyzed with the help of a statistician using Statistical Package for Social Sciences (SPSS) program, software for windows version 21.0 Results: Results showed that participant’s responses to five of the twelve items on patient safety were found to have significant associations with residential setting. Rural participants were less likely to disagree with statements on availability of signage at the entrance of health establishment that indicates times when various services are offered, availability of the security guards to ensure patient safety, warning signs always put in place when the floors are wet, availability of at least one toilet for disabled patients in the health establishment and the fact that health professionals are always wearing name tags. This means that patient safety and security is practiced and implemented at the rural facilities according to the national core standards. The findings of the study confirmed that 13 items out of 19 under care and attitudes were found to have significant associations with residential setting. The items were patients spending less than 2 hours in the health facility; staff treating patients politely, illness being explained clearly to the patients, and ability of the patients to ask questions about their illness. Other items included nursing attitudes during opening and closing times of the health establishment, staff responding well when requested to assist, patients are being treated with empathy, patients are addressed by names and patients are being given all the treatment that they need, nurses explains the treatment side effects, and explains how to deal with side effects. This means that responses to these items depend on whether the patient is from a rural or urban clinic. Rural communities were found to be vi less likely to disagree with statements as compared to urban communities. This means that nurses are compliant with nursing care and attitudes in rural clinics. Findings of the study with respect to facility cleanliness, shows that there is no significant associations between the responses to the items which are: surroundings of the clinic are free of unpleasant smells, grounds of the clinic are clean, safe and clean grounds, bin waste inside and outside storage poses no health risks, and setting were detected. This means that the facilities are and cleanliness status remains the same across the residential settings. However, the younger age group was found be significantly more likely to disagree that toilets are clean and odorless and that grounds are safe and clean compared to the older age group. This suggests that the environment is clean except the toilets. Conclusion: Staffs at the facilities are at times ignorant and have negative attitudes at the opening and closing times and facilities have been reported to have long waiting times. The study indicated that the safety and security measures in the urban health facilities are not all practiced according to the National Core Standards checklist/Assessment tool, particularly wet warning signs, disabled toilets, and wearing of nametags. Majority of the participants indicated that, the status of cleanliness was on par at the urban and rural facilities.

Laccases are employed in several industrial processes that play a key responsibility in transformation of life and making the environment a better place. Bacteria have been described as best producers of laccases with a potential in the industrial scale processes. Laccase was produced from different bacterial isolates identified and named as Bacillus sp. strain GFN1 isolated from soil sample, Bacillus sp. strain GLN and Streptomyces sp. strain LAO both isolated from decaying wood samples in Raymond Mhlaba local municipality with accession numbers MK290988 to MK290990 respectively, as identified by partial sequencing, these were the best producers some of which were positive for Napthol and guaiacol; even upon quantitative screening they were better laccase producers. For quantitative laccase screening, 2,2'-azino-bis(3-ethylbenzothiazoline-6- sulphonic acid) was utilised as the substrate for laccase assays. These laccase producing bacteria were subjected to optimization of growth conditions using submerged fermentation which increased the activity of the produced laccase in great amounts. In optimizing basal medium growth conditions where laccase was harvested after every 72 hours where optimal activity was 16 obtained, studying several factors such as pH which turned out to be pH 5 for all isolates, effect of supplemented carbon and nitrogen sources with the be best being lactose and urea respectively with their effective concentrations using lignin as the main carbon and nitrogen source. Copper sulfate was used as the main inducer and the species preferred guaiacol and ferullic acid and the Fe2+ asthe best supplemented metal ion. The time course was done investigating parameters such as cell growth which was determined by observing the optical density, laccase activity, protein concentration and pH and the presented results suggested that when there was an increase in cell growth, enzyme activity decreased pH had no much effect on the enzyme production as it was almost stable all the time with protein concentration exhibiting no direct effect on enzyme activity also. Characterization of the crude enzyme was done to check the stability of the enzyme produced in various parameters. The enzymes produced by the different strains were thermophilic as they were able to withstand elevated temperatures between 90 and 100 C, with pH stability within an extensive variety of alkaline pH, typical of most bacterial laccases. Various metal ions affected the stability of the enzyme with CuSO4 increasing the stability of two of the bacterial enzyme and appeared to slightly decrease the stability of one enzyme. The studied inhibitors only decreased the stability on the enzyme and couldn’t completely inhibit the enzyme, and the enzymes showed specificity towards varying substrates. The studied bacterial laccases exhibit tremendous characteristics which are of great significance in the industries and will add to the novelty of bacterial laccases and their stability amongst the most studied fungal laccases.

- Description: The aim of the current study was to assess the supply chain corruption in the three metropolitan municipalities in the Gauteng Province of South Africa. Core to the assessment was to establish the causes and ramifications of supply chain corruption as well as the nature and extent of supply chain corruption in the three metropolitan municipalities. In order to meet the objectives of the current the study, a qualitative research approach underpinned by ethics and accountability theories was used. The study employed interviews and observation as a primary source of data collection as well as document review in a form of government documents, legislation and court case decisions as secondary source of data, which were then thematically analysed. The study pointed out that while supply chain corruption certainly negatively affects the day-to-day running of public affairs, it is actually the collapse of ethical behaviour together with the failure to uphold accountability and consequence management that has created fertile ground for supply chain corruption. It further, purported that in order to combat the scourge of supply chain corruption in all its manifestations, there is a need to install a Central Supplier Database application, which has been sufficiently tested to determine its effectiveness as blacklisted companies and their directors have a way of masquerading in another form, to do business with the state. South Africa needs the embodiment of ethical behaviour from its citizenry, along with anti-corruption policy enforcement and consequence management. The Kanyane Ethics Architecture should be launched in municipalities across the board as a comprehensive and all-encompassing mix model to prevent supply chain corruption, in its various manifestations, from taking place.
